six-WHEEL TRUCK. l

Specification of Letters latent.

Patented Dee. 17, 1918.

Application led November 24, 191?. Serial No. 203,677.

T all idiom. it may concern Be it known that l, FRANK H. KAYLER, a citizen ofthe United States, and resident or' Alliance, in the county of Stark and State of Ohio, havel invented certain new and useful Improvements in SiX-lVhecl Trucks, ol' which the folloving is a specification.

This invention relates to railway cur trucks, and more particularly to six-wheel ear trucks. i

@ne of the objects or my invention is to equalize the load on all wheels of a six- Wheel car truck Without the use of eomplicated levers lnothcr object is to improve the side bearing arrangement. l

Another object is to improve the truck arrangement for the transmission and disA tribution olf the load in a manner to meet the various requirements for successful commercial operation.

Generallyr speaking, these and other objects are accomplished by providing, in a sin-Wheel truck the combination of a side frame, a bridge or equalizer member operatively connected to said frame, and a bolster operatively connected to said bridge member in a manner to equalize the load on all of the Wheels.

The invention is illustrated on the accompanying sheets of drawings, in Which- Figure l is side elevation ot a six-Wheel truck embodying my invention;

Fig. 2 is a fragmentaryv plan View of 'the same;

ig. 5 is a sectional View taken in substantially the same plane as the one'sliown in Fig. 4 of a modilication ot' my invention; and,

Fig. Sis a sectional View taken in the plane of line 6-`3 ot Fig. 1.

The various novel features of mv invention "will be apparent from the following oleseription and drawings and will be partienlarly pointed out in the appended claims.

Rer'erringvto the ligures of the drawings. it. will be noted that l have provided a sixwheel truck including at each side a side frame including a plurality of members 10 and 11 pivotally connected, adjacent the middle wheels, at their inner ends by a pin 12. whereby the side frame members 10 and ll may oscillate in a vertical plane in accordance with track irregularities encountered when the grade of the road varies. These side 'trame members 10 and 11 have bolster openings 13 and 1l, respectivelyand spring openings 15 and 16, respectively. Mounted over the springs 8 and 9, which are located in the spring,r openings 15 and 1G, are caps 17 and 18 respectively,g having squared heads which tit intov grooved rccesses 19 and 2C] cspe tivel v, formed in 0pposite ends of an equalizer 21 which bridges the springs 8 and S). The top portion 22 of the equalizer 21 forms a side bearing for the ear, thus transferring the side. bearing load directly to the springs 8 and 9 withoutI transferr-ing this load through the bolster. .ln the upper side of the equalizer' 21. near the ends thereof there are provided pockets 23 and 2l. respectively. for the reception of bolster arms or members 25 and :26. respec.d tively, which are formed integrally with a central bolster 27,

lt will be, noted that the bolster openings 13 and l-'l are located centrally between the end and middle pairs ot wheels and that. the spring openings ,15 and lt are located at distances onethird from the end pairs of wheels and two-thirds from the central pair ot wheels, ln this manner the load is equalized on all wheels. The load from the eentral bolster 27 is transferred to the springs 8 and f) through the equalizer Q1, the biliurcatetl ends ot which rest on the spring plates or caps 17 and 18.

With this arrangement the holsters or bolster members 25 and 26 mav be combined into an intefral struf'ture With the central bolster 27. Une to the tact that the bolster arms Q5 and 25 are 'located centrallv between the rvlfieels. the size of the ends passingn through the side frame is not limited. lt is also obvious that with the arrangement as shown, it is unnecessary to use separate column guide pieces bolted on the end of the bolster, Whirh is necessary in some designs or six-wheel trucks. rlhe side 'frames are .maintained in vertical position in the same manner as all flexible side frames o this general type including the application of the load thereto at points below the journal boxes producing in eliect a pendulum arrangement.

Referring particularly to Fig. 5, I have shown therein a modification to be used in connection with a three-piece flexible bolster if used in the place of the unit bolster shown in the other iigures of the drawings. In the construction shown in Fig. 5, the ileXibility is yincreased between the equalizer and the end of the holsters 27 by means of the casting 28, the ends of the holsters and casting 2S having coiiperating curved bearing portions 29. In both of these constructions, the load is thus distributed equally upon the ends of the equalizer 2l, While the side motion and excessive flexibility are limited by recesses 30 in the holsters which interlock with the bridge member, as shown best in connection with Fig. 2 of the drawings.

By means of the arrangement of the parts in this six-wheel truck, the load is evenly distributed in asimple manner, avoiding a complicated system ot` levers which heretofore has been used. At the same time the transmission and the distribution of the load are improved, the parts being so connected land coperating in a manner to meet all of the requirements for successful commercial operation.

It is obvious that there may be various modifications of the invention herein particularly shown and described, and it is my intention to cover all such modifications which do not involve a departure from the spirit and scope of the invention as set forth in the following claims.
